To make the sauce, simply combine everything in a bowl and set aside.
Make the cornstarch dredge by whisking everything together in a shallow bowl or plate. I like to use a quarter sheet baking pan for it.
Cube your tofu into 1/2" cubes.
Dredge the tofu cubes in cornstarch mixture, coating each one thoroughly.
Heat up the frying oil in a large skillet to 350 F / 175 C. Carefully add the tofu cubes to the pan, you may need to do it in batches, make sure you don't crowd the pan.
Fry the tofu for about 2-3 minutes, then flip and fry for another 2-3 minutes or until the tofu is golden brown and crunchy. If frying in batches, let the tofu rest on a wire rack.
Once all tofu is fried, carefully add the oil to a metal bowl, and save the oil! Don't throw it out. You can reuse it a few more times!
Over medium heat, add the tofu back to the pan, and add the sauce. Coat the tofu thoroughly in the sauce, and stir over medium heat until it's a thick glaze, about 2-3 minutes.
Serve over rice, noodles or with veggies and enjoy!
